What type of diagram is used to indicate the location and actual termination of auxiliary devices?

The correct answer is the wiring diagram, as it serves the specific purpose of illustrating the connections and terminations of various devices within an electrical system. This type of diagram provides a detailed representation of how different components, such as switches, sensors, and relays, are wired together and where they are physically located. By showing the actual termination points of auxiliary devices, the wiring diagram facilitates installation, troubleshooting, and maintenance processes since technicians can reference this diagram to understand the exact configuration of the electrical system.

In contrast, the schematic diagram offers a more abstract representation of the circuit’s functionality, focusing on how components are interconnected logically rather than their physical layout. This diagram type does not present the precise locations or termination details of devices.

Pictorial drawings provide a visual representation of components as they appear in real life, but they lack the detailed connection information that is crucial for understanding circuit layouts comprehensively.

An electrical layout, while it may show the broader arrangement and positioning of electrical systems within a physical space, typically does not delve into the specifics of wiring and terminations for individual auxiliary devices. Hence, the wiring diagram stands out as the most appropriate choice for this particular purpose.
